In situ groundwater treatment technologies: Increased implementation through results of field-scale performance assessments
In situ groundwater treatment technologies are important components of groundwater remediation efforts at a wide variety of sites. Too often, however, innovative technologies are not given adequate consideration by consultants, regulators, and site owners due to a lack of conclusive evidence that they will be effective alternatives. Field-scale demonstrations of the efficacy of in situ remediation. Technologies are important for good engineering design. These types of projects provide an increase in the accuracy of conceptual models of the governing processes and can elucidate the practical aspects of full-scale implementation. Demonstration projects conducted at the field scale have a number of components necessary for assessing treatment performance. Depending somewhat on the technology, these can include: pre- and post-treatment sampling; detailed site characterization of stratigraphy and hydrogeology; and comparisons between predictions of engineering models and actual performance. Results of only a few technology demonstration projects have been described in the technical literature well enough to fill the gap between laboratory studies and full-scale trials. This paper highlights the results of a few relatively comprehensive performance assessments and identifies the information needed for future demonstration projects. Innovative technologies may be considered more often if demonstrations are conducted using a comprehensive assessment approach and if technology transfer reaches a broader audience of practitioners and regulators than is currently being achieved.
